If your dashboard shows a 30% dip in performance despite no changes to your ads, you are a victim of "Signal Loss." Since the iOS 14.5 update and subsequent Android privacy shifts, the link between an ad click and a purchase has been severed for ~40% of users.
The Solution: Conversions API (CAPI)
Pixel tracking is client-side (browser-based). CAPI is server-side. By sending purchase data directly from your server to Meta, you bypass browser blockers. We have seen CAPI implementation restore 15-20% of "lost" attribution within 7 days.
Action Steps:
- Verify your domain in Business Manager.
- Set up "Aggregated Event Measurement" for your top 8 events.
- Implement CAPI Gateway or a server-side container (GTM).
